During the past year or so, my oil pressure gage reading has been rising from the middle 50's to over 70. Since the gage stops at 70 this is worrisome.
I checked the pressure with a new gage screwed directly into the fitting at the rear of the motor, same place the sending unit screws into, and get a reading of about 65. I don't see any signs of new oil leaks, so what might be happening here, and should I worry? The cars runs super and I don't hear noises that shouldn't be there. Of course, the Hall off road exhaust system drowns out almost every noise other than my wife yelling at me to shut the damn thing off.
I would think that more miles on the motor or pump would eventually lower oil pressure, or is this like the human body that gets clogged arteries from too much good care?
